Another royal baby has arrived! Lord Freddie Windsor and wife Sophie Winkleman welcomed their first child, a baby girl, in L.A. on Thursday, Aug. 15.

The royal British couple's daughter weighed 7 lbs. at birth, and was named Maud Elizabeth Daphne Marina. She is 42nd in line to the throne.

Windsor, 34, and actress Winkleman, 33, wed at Hampton Court Palace in London in September 2009. According to The Daily Mail, the couple is currently living in L.A. while Winkleman, who has appeared on Two and A Half Men, pursues her acting career and Windsor works as a financial analyst.

Baby Maud is the first granddaughter for Windsor's parents, Prince and Princess Michael of Kent.

A source close to the new grandparents tells Us Weekly "they're thrilled" and "can't wait to visit baby Maud next week."
